Description

Technical Field

[0001] The utility model relates to the technical field of steering yokes, in particular to a high-strength and lightweight automobile steering yoke. Background Art

[0002] The steering yoke is a key component in a vehicle's steering system. It typically has a fork-shaped structure and is primarily used to connect the steering knuckle to other related components, such as the steering rod. Its shape allows it to effectively transmit force and motion during steering.

[0003] The steering yoke connects the knuckle to other components in the steering system. If the yoke lacks stability and strength, the steering wheel slipping during a collision can generate significant impact, causing deformation or damage. Once the steering wheel slips and loses control during a collision, the driver loses control of the vehicle's direction and the vehicle may veer erratically, increasing the severity and complexity of the accident. Therefore, we developed a high-strength, lightweight automotive steering yoke. Utility Model Content

[0004] The purpose of the present invention is to provide a high-strength and lightweight automobile steering yoke to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a high-strength and lightweight automobile steering yoke, comprising:

[0006] A steering knuckle journal, wherein the steering knuckle journal is connected to a connecting shaft, and the connecting shaft is connected to a fork ear, wherein two fork ears are provided, and both fork ears have ear holes on both sides. A buffer assembly is provided on the connecting shaft, and the buffer assembly includes an elastic buffer rod, wherein the elastic buffer rod is located between the two fork ears, and the elastic buffer rod is made of a memory alloy;

[0007] A fixing plate is provided on the side of the elastic buffer rod away from the connecting shaft, and a connecting component is provided at the connection between the fixing plate and the elastic buffer rod. A sliding groove is provided on the top of the fixing plate, and a slider is slidably connected in the sliding groove. There are two sliders, and a spring is fixedly connected between the two sliders. A damping is provided in the spring. A connecting rod is connected to the slider, and a splint is connected to the side of the connecting rod away from the slider, and a first screw is threadedly connected between the splint and the fork ear.

[0008] As a preferred embodiment, two buffer components are provided, and the two buffer components are respectively located on both sides of the connecting shaft, and the elastic buffer rod is made of elastic material and will be tightened as the fork ear rotates.

[0009] The above technical solution is adopted: by arranging buffer components on both sides, the impact force generated can be absorbed no matter which side the steering wheel collides to protect the internal components.

[0010] As a preferred embodiment, the connecting assembly includes a ring, which is mounted on the elastic buffer rod, and fixed seats are fixedly connected on both sides of the ring, and the fixed seat and the bottom of the fixing plate are threadedly connected with a second screw.

[0011] The above technical solution is adopted: by setting a connecting component, the elastic buffer rod and the fixed plate are connected and limited.

[0012] As a preferred embodiment, the elastic buffer rod is sleeved with a heat-conducting ring, and the heat-conducting ring is made of elastic material.

[0013] The above technical solution is adopted: by setting a heat-conducting ring, since the elastic buffer rod is made of memory alloy, its crystal structure changes and becomes harder under the high temperature and high stress generated by the collision, thereby limiting the abnormal movement of the steering yoke and reducing the possibility of the steering wheel slipping and losing control. However, heat is also generated when the engine is running at high speed, so the heat-conducting ring is designed to absorb the heat on the elastic buffer rod to prevent it from becoming hard due to the heat generated by the engine.

[0014] As a preferred embodiment, a partition assembly is provided on the connecting shaft, and the partition assembly includes a temperature detector. A clamping assembly is provided on the side of the connecting shaft close to the temperature detector, a spring is provided on the side of the elastic buffer rod close to the thermal conductive ring, a limiting member is provided on the side of the connecting shaft close to the spring, an insert is connected to the side of the spring close to the thermal conductive ring, and a groove is provided on the side of the thermal conductive ring close to the insert.

[0015] The above technical solution is adopted: by setting up a partition assembly, since the heat generated by the engine is different from the heat generated during a collision, when the temperature detector detects the heat generated by the collision, the limiter will open, so that the spring will bounce the insert into the groove, and then the heat conduction ring will be stretched open, and no heat will be conducted. Then the elastic buffer rod will become hard, thereby limiting the abnormal movement of the steering yoke.

[0016] As a preferred embodiment, the clamping assembly includes a rotating shaft, which is rotatably connected to the connecting shaft. A torsion spring is provided on the rotating shaft, and a limiting plate is rotatably connected to the torsion spring.

[0017] The above technical solution is adopted: the temperature detector is fixed and limited by setting a clamping component.

[0018] As a preferred embodiment, connecting grooves are provided on both sides of the fork ears.

[0019] The above technical solution is adopted: by providing a connecting groove, the weight of the steering yoke can be reduced, and its own inertia is reduced. During the vehicle steering process, the inertia force that the steering system needs to overcome is also reduced. This allows the driver to control the steering angle of the wheel more accurately and sensitively when turning the steering wheel.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are:

[0021] In the present invention, by providing a buffer assembly, the steering wheel can absorb some of the energy through its own deformation when it collides, reducing the impact force transmitted to other components of the steering system. By providing a heat-conducting ring, since the elastic buffer rod is made of a memory alloy, its crystal structure changes under the high temperature and high stress generated by the collision, becoming harder, thereby limiting the abnormal movement of the steering yoke and reducing the possibility of the steering wheel slipping and losing control. However, heat is also generated when the engine is running at high speed. Therefore, the design of the heat-conducting ring absorbs the heat from the elastic buffer rod and prevents it from becoming hardened due to the heat generated by the engine. This solves the problem that the steering yoke plays the role of connecting the steering knuckle and other components in the steering system. If the steering yoke is not stable and strong enough, when the steering wheel slips in the event of a collision, a huge impact force will be generated, causing it to deform or damage. Once the steering wheel slips and loses control in the event of a collision, the driver will not be able to effectively control the direction of the vehicle, and the vehicle may steer arbitrarily, increasing the severity and complexity of the accident.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 3 As shown, a high-strength and lightweight automobile steering yoke includes a steering knuckle journal 1, a connecting shaft 2 connected to the steering knuckle journal 1, a fork ear 3 connected to the connecting shaft 2, two fork ears 3 are provided, and ear holes 10 are opened on both sides of the two fork ears 3. A buffer assembly 4 is provided on the connecting shaft 2, and the buffer assembly 4 includes an elastic buffer rod 41. The elastic buffer rod 41 is located between the two fork ears 3, and the elastic buffer rod 41 is made of memory alloy;

[0031] A fixing plate 42 is provided on the side of the elastic buffer rod 41 away from the connecting shaft 2, and a connecting assembly 8 is provided at the connection between the fixing plate 42 and the elastic buffer rod 41. A sliding groove 49 is provided on the top of the fixing plate 42, and a slider 43 is slidably connected in the sliding groove 49. There are two sliders 43, and a spring 44 is fixedly connected between the two sliders 43. A damper 45 is provided in the spring 44. A connecting rod 46 is connected to the slider 43. A clamping plate 47 is connected to the side of the connecting rod 46 away from the slider 43. A first screw 48 is threadedly connected between the clamping plate 47 and the fork ear 3. A heat conducting ring 7 is sleeved on the elastic buffer rod 41, and the heat conducting ring 7 is made of elastic material.

[0032] Specifically, when the steering wheel collides, the connecting rods 46 on both sides will first drive the two sliders 43 to squeeze the middle spring 44 and the internal damping 45, thereby absorbing most of the impact force and ensuring that the internal components will not be damaged to the greatest extent. Then, since the elastic buffer rod 41 is made of memory alloy, its crystal structure changes under the high temperature and high stress generated by the collision of the vehicle, becoming harder, thereby limiting the abnormal movement of the steering yoke and reducing the possibility of the steering wheel slipping out of control. However, heat will also be generated when the engine is running at high speed, so the design of the heat conductive ring 7 is to absorb the heat on the elastic buffer rod 41 to prevent it from becoming hard due to the heat generated by the engine.

[0033] like Figure 2 As shown: Two buffer assemblies 4 are provided, and the two buffer assemblies 4 are respectively located on both sides of the connecting shaft 2, and the elastic buffer rod 41 is made of elastic material and tightens as the fork ear 3 rotates. By providing the buffer assemblies 4 on both sides, the impact force generated can be absorbed regardless of which side the steering wheel collides, thereby protecting the internal components;

[0034] like Figure 4 As shown: the connecting assembly 8 includes a collar 81, which is sleeved on the elastic buffer rod 41. Both sides of the collar 81 are fixedly connected to a fixing seat 82. The fixing seat 82 and the bottom of the fixing plate 42 are both threadedly connected with a second screw 83. By setting the connecting assembly 8, the elastic buffer rod 41 and the fixing plate 42 are connected and defined.

[0035] like Figure 4 and Figure 5 As shown: a partition assembly 5 is provided on the connecting shaft 2, and the partition assembly 5 includes a temperature detector 51. A clamping assembly 6 is provided on the side of the connecting shaft 2 near the temperature detector 51. A spring piece 52 is provided on the side of the elastic buffer rod 41 near the heat-conducting ring 7. A limiting member 53 is provided on the side of the connecting shaft 2 near the spring piece 52. An insert 54 is connected to the side of the spring piece 52 near the heat-conducting ring 7. A groove 55 is provided on the side of the heat-conducting ring 7 near the insert 54. Since the heat generated by the engine is different from the heat generated during a collision, when the temperature detector 51 detects heat generated during a collision, the limiting member 53 will open, so that the spring piece 52 will bounce the insert 54 into the groove 55, and then the heat-conducting ring 7 will be stretched and no longer conduct heat. Then the elastic buffer rod 41 will become hard, thereby limiting the abnormal movement of the steering yoke;

[0036] like Figure 5 As shown: the clamping assembly 6 includes a rotating shaft 61, which is rotatably connected to the connecting shaft 2. A torsion spring 62 is provided on the rotating shaft 61, and a limiting plate 63 is rotatably connected to the torsion spring 62. By setting the clamping assembly 6, the temperature detector 51 is fixed and limited.

[0037] like Figure 1 As shown, connecting grooves 9 are provided on both sides of the fork ears 3. By providing the connecting grooves 9, the weight of the steering yoke can be reduced, and its own inertia is reduced. During the vehicle steering process, the inertia force that the steering system needs to overcome is also reduced. This allows the driver to control the steering angle of the wheel more accurately and sensitively when turning the steering wheel.

[0038] The working principle provided by the present invention is as follows: by providing a connecting groove 9 on the fork ear 3, the weight of the steering yoke can be reduced, and its own inertia is reduced. During the vehicle steering process, the inertia force that the steering system needs to overcome is also reduced, which enables the driver to control the steering angle of the wheel more accurately and sensitively when turning the steering wheel. First, by setting a connecting component 8, the elastic buffer rod 41 and the fixed plate 42 are connected and limited. When the steering wheel collides, the connecting rods 46 on both sides will first drive the two sliders 43 to squeeze the middle spring 44 and the internal damping 45, thereby absorbing most of the impact force and ensuring that the internal components will not be damaged to the greatest extent. Then, since the elastic buffer rod 41 is made of memory alloy, when Under the high temperature and high stress generated by a vehicle collision, its crystal structure changes and becomes harder, thereby limiting the abnormal movement of the steering yoke and reducing the possibility of the steering wheel slipping and losing control. However, heat is also generated when the engine is running at high speed, so the design of the heat-conducting ring 7 is to absorb the heat on the elastic buffer rod 41 to prevent it from becoming hard due to the heat generated by the engine. Since the heat generated by the engine is different from the heat generated during a collision, when the temperature detector 51 detects the heat generated by the collision, the limiter 53 will open, and the spring 52 will bounce the insert 54 into the groove 55, and then the heat-conducting ring 7 will be stretched and no longer conduct heat. Then the elastic buffer rod 41 will become hard, thereby limiting the abnormal movement of the steering yoke.

[0039] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention.
